WINDING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 614,830, dated November 29, 1898. Application filed August 10, 1896. Serial No. 602,252. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE LooMIs BROWN- ELL, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in \Vinding Mech anism, of which the following is a specification, accompanied by drawings forming a part of the same and representing a winding mechanism embodying my invention.

My invention relates to that part of a twisting mechanism for twisting twine or cord which is employed in winding the twisted cord upon a winding-spool, and particularly to that portion of the winding mechanism which is employed to traverse the twisted cord along the winding-spool during the operation of winding, so the cord will be laid uniformly thereon; and the object of my invention is to provide a traversing device which is capable of being rotated at a high rate of speed without increasing the friction of the moving parts and maintain a perfect balance during its rapid rotation, and I accomplish these results by means of mechanism hereinafter described and represented in the accompanying drawings, in which Figure 1 represents aflier-frame and wind ing-spool carried therein of a twisting-machine for twisting cord or twine, said flier being shown in elevation. Fig. 2 represents an elevation of the flier-frame shown in Fig. 1,, showing a side view at right angles to that represented in Fig. 1. Fig. 3 is a central vertical sectional view of the flier-frame with the winding-spool shown entire. Fig. i is a top view of the flier-frame and winding-spool shown in section on line 4 4, Fig. 3. Fig. 5 represents the under side of the upper head of the flier-frame, and Fig. 6 is a diagrammatic view showing the flexible connection between the traversing ring and the reciproeating scored pulley by which the traversing ring is actuated.

Similar letters and figures refer to similar parts in the different figures.

Referring to the drawings, A denotes the revolving flier-frame of an ordinary twisting-machine for twisting twine or cord, and B the winding-spool, upon which the twisted cord 0 is wound.

In the operation of the machine the spool B is rotated to wind up the twisted cord, and the flier-frame A is also rapidly rotated to twist the cord 0, which is fed to the flierframe concentrically with its axis of rotation and carried over the guide-pulleys D and D to the winding-spool B in a line at right angles with the axis of the spool, so as to be wound as the spool is rotated, this partof the mechanism being the same as that in winding machines now in common use. The guide-pulley D is given a traversing motion parallel with the axis of the winding-spool to cause the twisted cord to be evenly laid upon the winding-spool B by means of the mechanism which forms the subject of my present invention and consisting of a ring E passing outside thevfour rods F, which unite the lower headGand upperhead G of a flierframe.

Attached to the inner side of the ring E are U-shaped straps H, which inclose the rods F and bear against the opposite sides of the rods, so that as the flier-frame rotates the ring E will be rotated by the rods F and be held from independent rotation by the contact of the sides of the U-shaped straps with the sides of the rods F, which are preferably slightly flattened.

The space inclosed by the U-shaped straps H in a radial direction is slightly greater than the diameter of the rods F, leaving a clear space H between the U -shaped strap and the inside of the rod, and also a clear space H between the outside of the rod F and the inside of the ring E, thereby allowing a slight radial movement of each of the rods F, caused by vibration or by centrifugal force incident tate concentrically with the axis of the winding-spool, notwithstanding the vibration of the rods F.

The guide-pulley D rotates upon a stud held in a bracket 1, attached to the inside of the ring E, and upon the diametrically oppo- I beneath the inside of the upper flier-head G and carried upon a spindle L, passing concentrically through the hub G of the upper flier-head and actuated by any suitable conneeting mechanism-such, for example, as that shown and described in Patent No. 560,680, granted to me May 26, 1896.

The cord K is attached at its ends to the rim of the scored pulley L at the points 1 and 2, Figs. 5 and 6. From the point of attachment 1 it passes around the guide-pulleys 3, 4, 5, and 6, (represented by broken lines in Fig. 6,) then half-way around the scored pulley L, crossing the same at 7, Fig. 6, then around the guide-pulleys 8, 9, 10, and 11, and

around the scored pulley L to the point of attachment 2, so that as the scored pulley L is reciprocated back and forth a reciprocating motion will be imparted to the cord K and a traversing movement given to the ring E sufficient to lay the twisted cord evenly between the heads of the winding-spool.

I find it convenient to employ the U -shaped straps H, attached to the inside of the ring E; but it is obvious that two parallel pins might be used, projecting from the inside of the ring E and in contact with the sides of the rodsF, or the ring might be enlarged and provided with openings to receive the rods. The ring E and straps H inclose a radiallyelongated opening, in which the rods F are inclosed, so the ring will be held from rotatin g in either direction independently of the rods and at the same time allow a slight radial motion of each of the rods independently of the ring, so that when the flier-frame is rapidly revolved the slight radial vibration of the rods F will not affect the position of the ring, which will be carried concentrically to its axis of rotation.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of a revolving flierframe comprising rods F parallel with its axis of rotation, a spool held in said flier-frame, a ring by which the cord is guided to said spool provided with radially-elongated openings inclosing said rods F, and means for moving said ring parallel with said rods, whereby said ring is rotated by said rods and maintained concentric with its axis of rotation, substantially as described.

2. The combination with a revolving flierframe comprising a spool-support by which a winding-spool is held concentrically in said frame and rods parallel with its axis of rotation, of a ring by which the cord is guided to the spool, said ring being held concentrically with the axis of said frame and having elongated radial openings which inclose said rods, whereby said ring isrotated by the rotation of said frame and said rods are allowed a slight radial movement in said openings, a reciprocating pulley and a flexible connection between said pulley and said ring, substantially as described.

Dated this 4th day of August, 1896.
